3. Society activity
She is a member of the JSAP(The Japanese Society of Applied Physics), MSJ(The Magnetic Society of Japan), JPS(The Physics Society of Japan), and IEEE Magnetic Society. She has been a committee of general affairs (2006-2011) and member of editorial board (2014-current) in MSJ, and a program committee(2008-2012) and an organizer of sectional committee Spintronics (2013-current) in JSAP, and sub-comittee of Joint MMM/INTERMAG2016.
Research Interests
  • Study of spintronic sensor and memory with ultra low power consumption
    keyword : sensor, memory, ultra low power consumption
  • Energy harvesting application from spintronics
    keyword : energy harvesting, spin current
Current and Past Project
  • The purpose of this study is to show the possibility which the Spin Seebeck power generation is enhanced from current pW-class to uW-class. By introducing the novel methods of fine structures and materials, we will enlarge the intrinsic parameters determining the generated power; Spin hall angular, spin mixing conductance and magnon temperature. After validation of the original ideas, the generated power potential will be estimated.
